Benefits of technology

[0015]The fan can also include a curved plate member to airflow and minimizes excess noise from air being moved from the blower wheel.
[0016]The lens cover can include a depressible and releaseable fastener for allowing the lens cover to be latched onto the grill cover by depressing a portion of the lens cover, and for allowing the lens cover to be removed by depressing the portion of the lens cover.

Problems solved by technology

There have been many problems with the prior art.
For example, many bath fans are difficult to be installed into a ceiling since the housings cannot be easily attached to different locations of joists in the ceiling.
If a joist is off center to the middle of bathroom ceiling the bath fan is not easy to center in the room.
Additionally, many of the bath fans have numerous parts which add extra manufacturing costs.
And as a result a bath fan that requires assembly of the bath fan at a job site will incur undesirable extra labor and material costs to install.
Additionally, many bath fans have to be wired to components inside of the housings which also requires extra expensive labor costs to make the connections onside during the installation of the bath fan.

Abstract

Apparatus, systems and methods of 50 CFM exhaust and ventilation fans for bathrooms with grill covers having removable light lens covers, and flaps/ears that allow the housings to mount directly to joists and/or other structural members inside of a ceiling or inside of a wall. The housing can include a mounting plate having a motor with attached impeller thereon, wherein the mounting plate with motor and attached impeller and electrical connectors can be removed as a single unit from the housing for accessing and inspecting interior wire connections during inspection and for ease in replacing parts such as burned out motors overtime.
